From the keyboard of Eric Osman   9/15/03


How often do we give up on a defense or an attack, grumbling to ourselves something like:


                oh well, that’s too large to be one of the known dead shapes”


How many groups could I have killed or saved, that I didn’t bother trying, due to such an attitude ?


Consider this situation:


                White to Play



Suppose white ataris the single stone inside ?  what happens ?  White seems to be pushing from behind.


Do the resolute ataris get white anywhere ?


You can send me email telling me what you find.
